NOTHING EXISTS THAT IS NOT SHIVA includes jewels of wisdom from Shiva Sutra, Gurugita, Vijnanabhairava and few other texts with Muktananda's enlightening commentaries.Muktananda keeps on reminding the reader that Shiva is everywhere present and that a spiritual aspirant has to keep this always in his awareness. Here is an example related to working successfully with mantras:"The one who repeats the mantra is Shiva, the mantra Namah Shivay is Shiva, and the Lord of the mantra - its goal - is Shiva. The secret of the realization of a mantra lies in repeating it, having identified oneself completely with Shiva. In the Svacchanda Tantra, Lord Shiva says:'O Goddess, only he who knows that Shiva is within himself as himself realizes the goal of the mantra.'"The book is to be read, re-read, savored, absorbed and, of course, applied. As I read it once I found joy bubbling within me. I'll be reading it many more times.
